BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a heat dissipation base seat, and more particularly to a heat dissipation base seat having four extension arms respectively extending from four corners of the main body. Two bent sections are respectively disposed on two sides of each extension arm to increase the structural strength of the heat dissipation base seat.

2. Description of the Related Art

It is known that any existent electronic equipment or device includes various electronic components for operation. In operation, the electronic components will generate heat, which needs to be dissipated by means of a heat dissipation unit. The conventional heat dissipation units include heat sink, radiating fin assembly, heat pipe, heat dissipation plate and heat spreader. The sizes and specifications of the heat-generating electronic components vary and it is impossible to directly assemble the heat dissipation unit with the electronic component. It is necessary to first assemble a base seat with the heat dissipation unit and then connect the base seat with the electronic component to dissipate the heat. After the base seat is connected with the electronic component, it is necessary to further secure the base seat to the electronic component. Four extension arms respectively extend from four corners of the base seat. A hole is formed at a free end of each extension arm. Threaded fastening members are passed through the holes to lock the base seat on a circuit board in which the electronic component is plugged.

The conventional base seat is made of board material by means of pressing. The extension arms of the base seat are slender structures with poor structural strength. Therefore, when locked, the extension arms are subject to deformation of external force to cause defective product. As a result, the assembling process is inconvenient and the manufacturing cost is increased.

SUMMARY OF THE INVENTION

It is therefore a primary object of the present invention to provide a heat dissipation base seat, which has higher strength.

To achieve the above and other objects, the heat dissipation base seat of the present invention includes a main body. A first extension arm, a second extension arm, a third extension arm and a fourth extension arm respectively extend from four corners of the main body. Two first bent sections respectively extend from two sides of the first extension arm. Two second bent sections respectively extend from two sides of the second extension arm. Two third bent sections respectively extend from two sides of the third extension arm. Two fourth bent sections respectively extend from two sides of the fourth extension arm. At least one locating hole is formed at a free end of each of the first, second, third and fourth extension arms, which free end is distal from the main body.

By means of the first, second, third and fourth bent sections, the structural strengths of the extension arms are greatly increased to minimize the possibility of deformation of the extension arms under external bending stress.

Two third bent sections 131 respectively extend from two sides of the third extension arm 13. Two fourth bent sections 141 respectively extend from two sides of the fourth extension arm 14. At least one locating hole 15 is formed at a free end of each of the first, second, third and fourth extension arms 11, 12, 13, 14, which free end is distal from the main body 1.

The first, second, third and fourth bent sections 111, 121, 131, 141 are formed on the longer lateral sides (long sides) of the first, second, third and fourth extension arms 11, 12, 13, 14 by bending.

Please now refer to FIG. 2, which is a perspective view of a second embodiment of the heat dissipation base seat of the present invention. The second embodiment is partially identical to the first embodiment in structure and thus will not be repeatedly described hereinafter. The second embodiment is different from the first embodiment in that the first bent sections 111 have a first folded edge 1111 and a second folded edge 1112 disposed on two sides of the first extension arm 11 respectively. The first and second folded edges 1111, 1112 respectively inward extend from outer sides of the first extension arm 11 toward each other.

The second bent sections 121 have a third folded edge 1211 and a fourth folded edge 1212 disposed on two sides of the second extension arm 12 respectively. The third and fourth folded edges 1211, 1212 respectively inward extend from outer sides of the second extension arm 12 toward each other.

The third bent sections 131 have a fifth folded edge 1311 and a sixth folded edge 1212 disposed on two sides of the third extension arm 13 respectively. The fifth and sixth folded edges 1311, 1312 respectively inward extend from outer sides of the third extension arm 13 toward each other.

The fourth bent sections 141 have a seventh folded edge 1411 and an eighth folded edge 1412 disposed on two sides of the fourth extension arm 14 respectively. The seventh and eighth folded edges 1411, 1412 respectively inward extend from outer sides of the fourth extension arm 14 toward each other.

Please now refer to FIG. 3, which is a perspective view of a third embodiment of the heat dissipation base seat of the present invention. The third embodiment is partially identical to the first embodiment in structure and thus will not be repeatedly described hereinafter. The third embodiment is different from the first embodiment in that the first bent sections 111 have a first folded edge 1111 and a second folded edge 1112 and a first recess 1113 and a second recess 1114. The first recess 1113 is formed on the first folded edge 1111 and the second recess 1114 is formed on the second folded edge 1112.

The second bent sections 121 have a third folded edge 1211 and a fourth folded edge 1212 and a third recess 1213 and a fourth recess 1214. The third recess 1213 is formed on the third folded edge 1211 and the fourth recess 1214 is formed on the fourth folded edge 1212.

The third bent sections 131 have a fifth folded edge 1311 and a sixth folded edge 1312 and a fifth recess 1313 and a sixth recess 1314. The fifth recess 1313 is formed on the fifth folded edge 1311 and the sixth recess 1314 is formed on the sixth folded edge 1312.

The fourth bent sections 141 have a seventh folded edge 1411 and an eighth folded edge 1412 and a seventh recess 1413 and an eighth recess 1414. The seventh recess 1413 is formed on the seventh folded edge 1411 and the eighth recess 1414 is formed on the eighth folded edge 1412.

In the present invention, structural strength of the first, second, third and fourth extension arms 11, 12, 13, 14 of the main body 1 is increased so that the first, second, third and fourth extension arms 11, 12, 13, 14 are prevented from being deformed under external bending stress. Moreover, due to the structural design of the extension arms, the structural strength of the main body is greatly increased. This can make the main body 1 more tightly contact the heat source to reduce thermal resistance.
